django-haystack returning unexpected results

I am trying to integrate django-haystack on a blog.



Here is my Post model:



class Post(models.Model):
slug = models.CharField(max_length=2000)
title = models.CharField(max_length=2000)
content = models.TextField(blank=True)
created_on = models.DateTimeField(auto_now_add=True)
updated_on = models.DateTimeField(auto_now=True)
user = models.ForeignKey(UserProfile, on_delete=models.CASCADE)

def __str__(self):
return self.title


Here is the how code in search_indexes.py file:



class PostIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.EdgeNgramField(document=True, use_template=True)
title = indexes.CharField(model_attr='title')
content = indexes.CharField(model_attr='content')


def get_model(self):
return Post

def index_queryset(self, using=None):
"""Used when the entire index for model is updated."""
return self.get_model().objects.filter(created_on__lte=datetime.datetime.now())


As you can see, I am using EdgeNgramField type to search for partial terms.



Now if I search for the term elastic, as expected, haystack returns post containing elastic somewhere either title or content field. However, haystack also returns some additional posts which do not have the term elastic neither in title or nor in content.



How can I fix this?



I have tested this code on: django-haystack (2.8.1), elasticsearch-2.4.2, and django-1.11



PS: This is my first encounter with elastic search.
